Corium
Corium
Corium (/ˈkɔːriəm/), also known as the dermis, is the second major layer of the skin. It is located beneath the epidermis and above the subcutaneous tissue.
Etymology
The term "corium" is derived from the Latin word "corium," meaning "leather" or "hide". This is likely due to the corium's role in providing strength and elasticity to the skin, similar to the properties of leather.
Structure
The corium is composed of two layers: the papillary dermis and the reticular dermis. The papillary dermis is the thin, upper layer that connects to the epidermis and contains capillaries and nerve endings. The reticular dermis is the thicker, lower layer that contains larger blood vessels, sweat glands, sebaceous glands, and hair follicles.
Function
The corium plays a crucial role in the body's temperature regulation, sensation, and protection. It provides nutrients to the epidermis, helps regulate body temperature through sweat glands, and contains nerve endings that allow for the sensation of touch, heat, cold, pain, and pressure.
